I dress light compared to most people I see. I don't see how people with insulated jackets and Turtle Fur neck warmers can stand it. I ride with an aggressive alpine style, though, which usually has me keeps me very warm...usually hot, sweaty, and panting in fact.

For most Pennsylvania days, I wear flyweight thermals top and bottom, under unisulated Gore-Tex pants and a jacket shell. Pit and croch zips usually open. As it gets colder, I wear heavier thermals with a zip neck and occassionally a fleece vest. If it's snowing (real or by snowguns), I'll also wear a super thin capilene balaclava pulled down to my chin. It's very rarely cold enough here to wear a fleece jacket beneath the shell. A helmet and googles add alot heat, too, usually not desired. The quick test to tell if I'm dressed right or not is to consider how I feel when I'm getting ready in the parking lot. I should be cold, almost to the point of shivering. If not, I'm overdressed and will cook on the slopes.

I don't like anything cotton, like T-shirts or sweatshirts. They suck up sweat and snow and get uncomfortable fast.
